I've just read Weapons of Math Destruction, by Cathy O'Neil. It's all about the mathematics behind the algorithms that underlie many of the processes in our lives today, including processing job applications and evaluating teachers' performance. Mathematics is regarded as objective, and therefore true, but the underlying assumptions, and the statistics on which the models are based, can be flawed, to put it mildly.
